-# ReclassX
+This tool helps you inspect raw bytes and interpret them as types (structs, arrays, primitives, pointers, padding) instead of just hex. It is essentially a debugging tool for figuring out unknown data structures either runtime or from some static source.
 
-An improvement over other reclass like editors.
+![Type chooser and struct inspection](docs/README_PIC1.png)
 
-https://github.com/IChooseYou/ReclassX/raw/main/video.mp4
+![VTable pointer expansion with disassembly preview](docs/README_PIC2.png)
 
-![screenshot](screenshot.png)
+![Split view with rendered C/C++ output](docs/README_PIC3.png)
 
+## Data Sources
+
+- **File** — open any binary file and inspect its contents as structured data
+- **Process** — attach to a live process and read its memory in real time
+- **WinDbg** — load `.dmp` crash dump files or connect to live debugging sessions
+
+## MCP Integration
+
+Built-in [Model Context Protocol](https://modelcontextprotocol.io/) bridge via `ReclassMcpBridge`. The server does not start by default and can be toggled from the File menu. It exposes all tool functionality to any MCP-compatible client (e.g. Claude Code) and falls back to UI prompts when the client requests something not yet covered by tools. To connect, add this to your MCP client config (e.g. `.mcp.json`):
+```json
+{
+  "mcpServers": {
+    "ReclassMcpBridge": {
+      "command": "path/to/build/ReclassMcpBridge",
+      "args": []
+    }
+  }
+}
+```
 ## Build
 
-Requires Qt 6, QScintilla, and MinGW on Windows.
+ 1. Prerequisites
 
-```
-cmake -B build -G Ninja
-cmake --build build
-```
+ - Qt 6 with MinGW - Qt Online Installer https://doc.qt.io/qt-6/qt-online-installation.html , note to select MinGW kit + CMake/Ninja from Tools section (online installers index: https://download.qt.io/official_releases/online_installers/)
+ - CMake 3.20+ - https://cmake.org/download/ - bundled with Qt
+ - windeployqt docs - https://doc.qt.io/qt-6/windows-deployment.html
+
+ 2. Quick Build (relies on powershell| for manual build skip to step 3)
+
+    git clone --recurse-submodules https://github.com/IChooseYou/Reclass.git
+    cd Reclass
+    .\scripts\build_qscintilla.ps1
+    .\scripts\build.ps1
+    ^ script above tries to autodetect Qt install (as we learned not everyone installs to C:/Qt/)
+
+ 3. Manual Build
+
+ Step by step for peoplewho want to run commands themselves:
+ 1. Clone with --recurse-submodules (+ fallback git submodule update --init --recursive)
+ 2. Build QScintilla: qmake + mingw32-make in third_party/qscintilla/src
+ 3. CMake configure + build with -DCMAKE_PREFIX_PATH
+ 4. optionallly windeployqt the exe
+

+ *   - A live process by PID via DebugCreate (non-invasive attach)
+ *   - A crash dump (.dmp) file via DebugCreate
+ *
+ * Target string format:
+ *   "tcp:Port=5055,Server=localhost"   - connect to WinDbg debug server (TCP)
+ *   "npipe:Pipe=name,Server=localhost" - connect to WinDbg debug server (named pipe)
+ *   "pid:1234"                         - attach to process 1234
+ *   "dump:C:/path/to/file.dmp"        - open dump file
+ *
+ * Threading: All DbgEng COM calls are dispatched to the thread that created
+ * the connection (DebugConnect/DebugCreate).  This is required because the
+ * remote transport (TCP/named-pipe) binds to the creating thread.  The
+ * controller's background refresh threads call read() which transparently
+ * marshals to the owning thread via BlockingQueuedConnection.
